Key result
Pocket-sized pTTE demonstrated 90% agreement with standard TTE for detecting cardiac abnormalities, outperforming ECG (65% agreement) and providing a superior negative predictive value of 92%.
Why the study?
Does pocket-sized portable transthoracic echocardiography (pTTE) provide accurate and cost-effective detection of cardiac abnormalities compared to standard TTE?
Cross-Sectional (n=200)
Does pocket-sized portable transthoracic echocardiography (pTTE) provide accurate and cost-effective detection of cardiac abnormalities compared to standard TTE?
Absolute Event Rate: 90% vs 65%
Pocket-sized portable echocardiography is an accurate and cost-effective initial screening tool for cardiac abnormalities, offering superior negative predictive value compared to standard ECG.

Supports pTTE screening potential over ECG; hypothesis-generating pending prospective validation before practice change.
Kitada et al. (2013) conducted a cross-sectional in cardiac abnormalities (n=200). pocket-sized portable transthoracic echocardiography (pTTE) vs. electrocardiogram (ECG) was evaluated on agreement with standard TTE in the detection of abnormal findings. Pocket-sized pTTE demonstrated 90% agreement with standard TTE for detecting cardiac abnormalities, outperforming ECG (65% agreement) and providing a superior negative predictive value of 92%.
